"The hunt for a perfect contraceptive has gone on for millennia. A new candidate is now on the horizon: a wireless implant that can be turned on and off with a remote control and that is designed to last up to 16 years. If it passes safety and efficacy tests, the device would be more convenient for many women because, unlike existing contraceptive implants, it can be deactivated without a trip to the clinic and an outpatient procedure, and it would last nearly half their reproductive life.

Developed by MicroCHIPS of Lexington, Massachusetts, the device will begin pre-clinical testing next year in the U.S. The goal is to have it on the market by 2018.

The idea for the device originated two years ago in a visit by Bill Gates and his colleagues to Robert Langer’s MIT lab. Gates and his colleagues asked Langer if it were feasible to create birth control that a woman could turn on and off and use for many years. Langer thought the controlled release microchip technology he invented with colleagues Michael Cima and John Santini in the 1990s and licensed to MicroCHIPS might offer a solution."
